Maybe Emacs can prompt the user to find/download the fonts that missing?

After many failed tries. I finally make Emacs a little faster after
customized the fontset. I have to find the font name and the script
name for each script. It a painful process. Maybe it is not Emacs'
fault, but I hope the customizing process could be automatically done.

The HELLO file opening still slow though.
